Why it matters
Music is part of the experience
Announcements turn into sales
Weekly deals, till guidance, fresh bakery: scheduled and one-touch announcements bring your shelf promotions to customers’ attention.
One change, every store
Upload a new promotional announcement once and it goes live within minutes at every store in the regions you choose.
Full visibility across the network
Which store is online, which is muted, which has been silent for a week: it is all in the dashboard, with alerts on WhatsApp.
Smart scheduling
A day at the supermarket
- Morning: fresh produce and bakery announcements with calm music.
- Lunch and evening peaks: an upbeat programme and till announcements.
- Weekends: the weekly promotion playlist and discount announcements start automatically.
- Closing: a “we close in 10 minutes” announcement.
Playlists are scheduled by date, time and weekday; when several apply, the most specific one plays. Transitions are automatic and smooth.
Sample announcements
One touch or text-to-speech
- “Fresh bread is out of the oven”
- “This week’s deals are on the shelves”
- “More tills are now open”
- “The store will close in 10 minutes”
Reliability
Music that never stops, and an alert the moment it does
Offline playback
Music is downloaded and played locally. Playback continues when the internet drops, and new content downloads in the background once it is back. Damaged or missing files are re-downloaded automatically.
Silence alerts
If a store sends no signal for 30 minutes, or the sound stays muted for 15 minutes, store, regional and brand managers are notified by e-mail and WhatsApp during business hours.
Timestamped report
Every track played at every store is archived daily in a PDF report sealed with a KamuSM qualified timestamp. Download it from the dashboard or request it on WhatsApp.
HYDW Music Player Dashboard
Every location on one screen
Manage playback with a brand, region and location hierarchy. Permissions are set by brand and module; alerts go separately to location, regional and brand contacts. On the web or in the iOS / Android management app.

Frequently asked questions
Common questions
Can promotional announcements play at set times?
Yes. Announcement files sit between music folders and campaign playlists are scheduled by date and time; they stop automatically when the campaign ends.
Can staff make instant announcements?
Staff can use the nine ready-made announcement buttons (Quick Start) on the player or type a text-to-speech announcement.
Can I run different promotions by region?
Yes. Playlists are assigned by region or store, so only stores in the promoted region play that announcement.
